ro'rATo-MAsnING MACHINE.

Application filed September 4, 1925. Serial No. 54 ,558.

This invention relates to machines for the preparation of food and has for its ob ect I the provision of a novel device by means of which boiled potatoes, carrots or other vegetables, fruit and the like may be mashed or riced in a very rapid and eflicientmanner.

An important object is the provision of a vegetable treating machine ofthis character-which is particularly designed for use in homes, restaurants or hotels, for the purpose of mashing or ricing potatoes and the like without it being necessary to perform the work manually by means of a beater or mash-er as is ordinarily necessary, there being consequently a great saving of time and labor as well as annoyance.

Another object of the invention is to provide a device of this character which will be more sanitary than the ordinary method inasmuch as it is unnecessary to touch the vegetables with the hands.

Yet another object is the provision of a machine of this type embodying a mashing chamber provided with closure means which not only operates to limit the quantity of vegetables or the like passing into the chamber but which acts also to retain the heat so that the food will be kept in a more palatable and attractive condition.

An additional'object is to provide a device of this character which will be simple and inexpensive in manufacture, easy to use, rapid in action, efficientand durable in service, and a general improvement in the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction, and the arrangement and combination of parts to be hereinafter more fully described and claimed, and

illustrated in the accompanying drawings. in which Figure 1 is a plan view of the device.

Figure 2 is a vertical longitudinal section.

Figure 3 is a vertical cross section looking in one direction, and

Figure 4 is a vertical cross section looking in the other direction.

Referring more particularly to the drawings, I have shown the device as comprising a receiving hopper 10 at the lower portion of which is mounted a cylindrical member 11 which may be formed integrally with the hopper or as a separate element attached thereto by any suitable means. The. assembled hopper and chamber member 1.1 are supported upon suitable legs 12 so thatthe member 11 will be elevated above the top] of the table or other support upon which the device is used to a sufficient extent that a receivingzdish may be disposed beneath the member 11. The hopper 10 'is preferably provided with a cover 13 which is removable when, it is desired to place potatoes, fruit or in fact any cooked materialfinto the hopper for the purpose of having it mashed or riced.

Located at the juncture of the hopper 10 with the cylindrical member ll'are'guides 14 within which is slidably mounted a closare. 01' cutoff plate 15 which is slidable' through a suitable slot 16 in one end of the device and which is equipped with a handle 17 whereby it may be moved back and forth as desired. The other end of this cutoff plate is preferably sharpened as indicated at 18 for a reason which will be hereinafter explained.

One end of the cylindrical member 11 is formed witha hole 19 and is equipped at its outside with a stationary nut 20 through which is screwed a threaded rod or screw 21 equipped at one end with a suitable handle 22 and provided at its other end with a swivelly mounted follower 23 restrained against rotation by meansof a projection 24 which extends between the guides 14.

the screw 21 in a counter-clockwise direction 18 thereof cutting through any material or vegetables which may be in the way. It is then merely necessary to grasp the handle 22 and rotate the screw 21 in a clockwise dropping down into whatever dish or other sition. The shield 26' operates to deflect the other material in: advance thereof being;

forced through the perforations 25 and receptacle may be placed in the proper pomaterial downwardly into the dish or receptacle. Obviously, if the device is used ina restaurant, hotel or the like, individual orders of vegetables or the like may be mashed or pressed out of the machine'as necessary, the existence of the closer plate 15 being of importance in that the heat of the vegetables or other articles will be retained so that their condition will be more attractive. Obviously, all the material Within the hopper will not necessarily be deposited into the cylindrical member or chamber at once and after the member 11 has been once emptied an additional supply maybe admitted thereto in exactly the same manner as above described. It is believed that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation.

tion and arrangement of parts as will not depart from the spirit of they invention or the scope of the subjoined claim.

Having thus described the invention, I claim:

A potato mashing machine comprising a supporting base, a horizontaliy arranged cylindrical compression chamber mounted on. the base and having one wall imperioratev and its other Wall formed with a plurality of. perforations, an inverted 'frusto pyramidal hopper located above and communicating with said chamber and coextensive in length therewith, pairs of spaced guide flanges located at the juncture of said chamber with the hopper, a cutoff plate 211."- cuate in cross section and complementary to the compression chamber slidably mounted for longitudinal movement along said pairs of guide flanges, a follower mounted Within said compression chamber and having a: portion extending into the opening at the" juncture of the hopper with the chambet' to prevent rotation, and an operating screw threaded through a nut member at the imperforate end of the chamber and having. a swivel connection with the follower;

In: testimony whereof I affix my signature'.
